BODY-CONTACT DEVICE non CHIROPRACTIC ADJUSTMENTMACHI'NES. T

-' Application filedDecember 12', 1922. Serial No. 606,389.

My invention relates to a body contact device for chiropracticadjustment machines and the objects of my invention are: first, toprovide a contact device of this'class of bridged'shapedand"construction which when applied to the regions of the spinal columncan be made tostraddle the column andapply equal pressure to both sidesthereof for loosening and adjusting the ligaments, muscles and tissuesin the vicinity of the spinal column preparatory to adjustment of thevertebrae; second, to provide a body contact device of this class ofvery yieldable construction so that When the same is applied as statedabove no injurious ef fects will be obtained; third, to provide anovelly constructed body contact device for chiropractic adjustmentmachines and fourth to provide a contact device of this class which isparticularly simple and economical of construction, durable, practical,eflicient and which will not readily deteriorate'or get out of order.

IVith these and other objects in view as will appear hereinafter myinvention consists of certain novel features of constructi-on,combination and arrangement of parts and portions, as will behereinafter described in detail andparticularly set forth in theappended claims, reference being had to the accompanying drawings and tothe characters of reference thereon which form a part of thisapplication, in which:

Figure 1 is an end view of the body contact device for chiropracticadjustment machines showing the same positioned on the end of thereciprocating plunger of the machine which plunger is shownfragmentarily and in section and showing by dotted lines a recededposition of portions of-the contact device when contacting with thebody; Fig. 2 is a side elevational view thereof shown apart from theplunger as shown in Fig. l and Fig. 3 is a plan view thereof.

Like characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

, The main contact member 1, plate2, bolt 3 and the nut 4 constitute theprincipal parts and portions of my body contact device.

The main contact member 1 is preferably made of a resilient pliablerubber and is substantially U-shaped in cross section, as shown, itswidth being somewhat less than its length. The leg portions 1 of the U-shapedniember 1 areslightly narrowerthanthe cross portion 1 whichconnects saidleg portions. The normallyupper or'outer side of the member1 is slightly curved as shown 1 best in Fig. 1 of the drawings. A plate)2 also the upper curved face of the member 1. 'A bolt 3 provided with asubstantially large headis inserted through the cross connecting portionof the U-shaped member from the normally lower or inner side thereof and.60 curved downwardly is positioned adjacent ext-ends through the sameand through the plate 2 positioned again-st the outer side.

The member 1. and the plate 2 are held in position relatively to eachother by the bolt extending therethrough and by the nut 1 screwed onsaid bolt. It will be noted that the screw portion of the bolt extends aconsiderable distance beyond the nutt and thus provides ample means forsecuring the body contact member as described to the reciprocatingplunger A of a chiropractic adjustment machine, for which I havemadeseparate application for Letters Patent, filed in the United StatesPatent Oflice, October 9, 1922, Serial No. 593,448, the outer end ofsaid plunger being provided with an internally threaded recess.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions I do not wish to be limitedtothi-s particular con struction, combination and arrangement but desireto 'include in the scope of my in vention, the construction, combinationand arrangement substantially as set forth in the appended claims.

It is obvious from this construction that there is provided .a contactdevice for chiropractic adjustment machinesof bridged construction whichwhen applied to the regions of the spinal column can be madeto straddlethe column and apply equal pressure to both sides thereof loosening andadjusting the ligaments, muscles and tissues in the vicinity of thespinal column, preparatory to the adjustment of the vertebrae; that Ihave provided a contact device of this class which is particularlyresilient of construction and will yield whenapplied to the body orbones of the body and is so constructed as to straddle sore or injuredpor tions of the body; that there is provided a novelly constructed bodycontact device for chiropractic adjustment machines and that there isprovided a contact device of this class which is particularly simple andeconomical of construction, durable, eflicient, practical and which willnot readily detericrate or get out of order.

Having thus described my invention vvhat '1 claim as new and desire tosecure by Letters Patent, is: H

1. In a device of the class described, the combination With a vibratingmember of a substantially U-shaped yieldable rubber body contact member,the leg and connecting portions thereof being of integral constructionand vthe length thereof being greater than the Width, a reinforcingresilient plate positioned bn the back side of said body contactn'uemberand a bolt means extending through the connecting portion ofsaid bodV contact member and said plate, securing the same together andadapted to be secured to one end of said vibrating member.

a In a device of the class described; the

ed With a securing portion extending eyond said plate adapted to securesaid supporting 1 member to said vibrating member.

In testimony whereof, I have hereunto set my hand at SanDiego,California this 5th day of December 1922. v

ERNEST H. ASHLOCK.
